LCMR-1000 is switching on/off a lamp, most of the times this is done through a LWST-605 on the wall.
The LCMR-1000 listens directly to the LWST-605 on the wall.
In addition Automagically controls this device with the tellstick of course.

If the lamp is turned on and off via the LWST-605 on the wall Automagically will never be able to determine if the lamp is on or off in a given point in time.

I have tried to configure the LWST-605 to trigger a event in Automagically to turn on the lamp, and this actually works, and then Automagically always knows if it is on or off. But this is rather limited in real-world usage,
it is to sluggish and slow so it annoys users and also i am concered about the fact that nobody will be able to turn lights on/off if the PI is down, or booting or down for maint. e.t.c. In addition congestion of the 433-mhz airspace is allready showing, especially since users tend to press buttons on the well with only a very short delay in between.

So what i want is:

* Define in automagically what switchers are controlloing which recievers
* Listen to the LWST-605 ON/OFF signals and mark the LCMR-1000 as ON/OFF respectivly.
* Really only LISTEN and update, i am planning for a total of 120 NEXA-units, i will have enough congestion allready.

Why i want it:

* I want to turn off lights if they have been ON for X minutes
* I want to be able to measure used electricity based on this info, if i would reliably know if a light was on or off this info would be really useful
* I want to do smarter management of lighting then just using Motion-sensors that turn the lights off after Xm, controlling Lights with both motion sensors and for ex. also LWST-605 could be really useful. Then the system could avoid turning off lights via the motion-sensor that where turned on manually just seconds earlier.

Any thoughts ?
Is the current data-model even supporting this ? I can see there is something modelled in the remotes, but not sure if it is relevant for this use.
If not supported, how should it be extended ?
Other thoughts ?

Not entirely correct, but depends on your set up. What you need to do is to make is to make Automagically send the same code as the LWST-605.
Enter signal debug and turn it on. Press your LWST-605 button and refresh the trace. You should now be able to see the house and unit code used by LWST-605.

I think you should look for a Z-Wave system instead, possibly improving your Pi with RaZberry - but then you need to abandon Automagically for now.
The Nexa protocol is way to error prone to handle what you want. I think you will be disappointed having invested in such a high amount of switches.
Z-Wave is better since it is a feedback system. Each switch acknowledges its actual status to the system. Also, with the right switches you can also get individual energy consumption. I really fancy this one: https://www.m.nu/wall-plug-fibaro-p-798.html

On the controller side, Fibaro Home 2 looks neat - but I like the modularity of the Zipabox (there is a module which can be used to control Nexa switches as well).

I think the NexaHome supports Z-Wave on the Pi/RaZberry- but I don't know to what extent.

I agree in general.
And Z-Wave being a actual standard is great. And in the long run 433 MHZ propitiatory stuff will eventually die even though NEXA could build a LCMR-1000 or similar that feeds back a signal if turned on/off.
But currently Z-Wave is at least 3-4 times more expensive, and i have no confidence that there will be software that can control this stuff the way i want to either.
automatically does not really do everything i want either, but i have confidence in the fact that i can modify it to do what i want and it seems properly designed so far.

Just did an total inventory, i will end up with about 27 (dual) wall-transmitters and maybe about 30-50 receivers, so its not that bad. In addition to that i have about 8 sensors currently though and will probably add another 10-15 of them.
In the long run i think you are right, and Z-Wave being a open standard it might actually be cheaper one day, but i want my toys NOW, and end of the day it's the cheapest hobby i ever had.
